TocZZ whom it may concern:

Be it kno'wn that l, HERBERT H. STEELE, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the "county of Kings andStatel of New York, have invented certain new and useful Improvements in Type-i/Vriting Machines, of which the following isa specification.

rlhis invention relates to typewriting machines and more particularly Vto the carriage feeding mechanism of such machines.

One-object of the invention is'to provide for aquick release of the carriage after the impact of the type against the platen and immediately after the lreturn4 movement of the linger key begins. y

A second lobject 'is' to provide means, in Connection with the "o'rdinaryI form of escapement mechanism, to release the carriage in letterv space direction immediately after the step ing dog has separated from the tooth of the escapenient wheel; in other `words, to secure the effect of a speed or reverse feedv escapement with a feed mechanism setas for the lordinary escapement.

A third object is to provide means to convert an ordinary escapement mechanism into a reverse feed escapement without altering the character or relative positions ofl the escapement members, that is, of either the dog member or members or the rack member or members.

Other objectswill appear subsequently.

To these ends the invention consists of certain arrangements of parts, combinations of devices and features of construction to be hereinafter described and more particularly pointed out in the concluding claims.

ln the accompanying drawings, illustrate ing one general form of my invention and forming a part of this specification, Figure l is a central, vertical, longitudinal, ysectional view of a typewijiting machine, in which the invention: is embodied, various parts of the' machine being omitted and broken away for the sake of clearness. i Figi 2 is a rear eleva-A tion of the machine shown in Fig. l.

the machine; 2, corner'postsi and 3, the top plate vor type ring. Y lheiiiqiger lkeys 4 are suitably connected kjey `tems 5 to key levers 6, the latter Xt'endirigc an front to rear of the machinex ndibeiiig pvoted at their rear ends on a tijinsversefulcrum rod 7. Each key lever is cpiinectedby an upright link 8 to a horizontaldiawbar 9 which is supported ateither-end. by one of .a pair of ,obliquely arranged 'paralleli-,inks 10, the 110 lower ends whereof are pivoted upon transverse fulcrum rods 11 and 12 Each draw bar is provided with a restoring spring 13 and has pivoted to it a connecting rod 14, which is pivotally secured at its upper end to one. of a series of circularly arranged type bars 15 carrying a type 15a journaled in hangers 16 secured 4to the type ring 3. Passing from side to side of the machine beneath and near the rear ends of the draw bars is a cylindrical rod 17 which controls the carriage feeding or letter spacing mechanism and isvsuitably secured at its ends in the front ends of a pair of upwardly and forwardly curving crank arms 1S. The rod 17 is termed the universal bar and this term is/com'monly applied to devices having like functions to the rod 17 whatever the form or construction of such devices may be. The crank arms 18 are fi):- edly mounted on a transverse rock shaft -19 which is suitably supported in thesides of the base of the machine and issurrounded by a restoring spring 20. Fixed on the rock shaft 19 at about the center of its length is a forwardly extendingfcrank arm 21 andpivoted to the latter at 22 is the lower end of the lower feed bar 23. Secured to the top plate 3 is a bracket 24 and suitably pivoted to the latter at 25 is an escapement bell crank 26, the upper end of the vertical arm whereof terminates in a rigid or holding dog 27. Pivctally secured to the end of the horizontal arm of the bell cr'an'k at 28 is a plate 29- which has suitably secured to its lower portion the upper end of the upper feed bar 30 and has pivoted in its upper portion at 31 a stepping or feeding dog 32, the movement of which is limited by stops'321L and 32'). The feed log is provided with a spring 33 which tei rvs to suing the dogabout its pivot in the dinftion of the arrow in Fig. 3 or in opposition to the direction of movement of the circular rack or escapement wheel 34, with a tooth cf which the feed dog is normally engaged. Upon being disengaged from the teeth of the latter by the downward. movement'of the Ifeed bar 30, the feed dog is moved by the spring 33 past the tooth with which it had been engaged. The upper end of the feed rod 30 is guided by the horizontal arm of the escapement bell crank 26 and upon the downward movement of said feed rod. to

' withdraw the feed dog from the escapement wheel the holding dog 27 at the top of the vertical arm of the bell crank is ,caused to move into `engagement with the escapement ball grooves which are oppositely disposed to similar grooves formed in the stationary carriage rails 42, the two sets of grooves formingraceways for the anti-friction balls 43. Pivotally secured to the carriage truck 41 is a platen carrier 44 supporting a platen 45 and provided with a front roll 46 which runs upon a xed track or way 47.. A band 48 connects the carriage truck with a spring drum 49, which latter. impels4 the carriage in the letter space direction and causes it to impart movement through the pinion 39 and shaft 37 to the escapement wheel 34. The foregoing devices are or may be of any suitable or known construction and are substantially such as are to be found in the typen is guided by the sides of said holes.

Caligraph.v It is, therefore, not deemed necessary to describe them with any greater degree of particularity. v.

Suita ly secured as by headed screws 50 to the top of thev rear of the base frame 1 of the machine are two loppositely disposed right-angled brackets or standards 51, lthe upper portion of the vertical arms 52 whereof are formed at either edge withlanges 53.

The flanges of theI forward bracket are bent rearward y at 1ighangles to the vertical arm 52 with which theyare connected, and the flanges' of the rear bracket are bent forwardly at right angles to the vertical arm 52 with which they are connected, thus forming opposing tracks or ways, as ,may be seen most clearlyT in Fig. 8. 'As best appears in Fig. 5, thetop of each standard is provided with a quadrant-like, horizontal ear orlug 54. The ends of these ears are perforated and the oerforations are tappedA to receive adjustab e limitin'gscrews 55. Thev tracklike upper portionsof the standards 51 Serveto support and guide between them aiclutch carrier 56. The carrier, which is shownin detail in Figs. 9 and 10, is preferably made of a single strip of metal-which. is bent or shaped into .the form of a box having two open sides. The ends of the strip of metal approach each other at about Vthe center of` the top of the box-like carrier andv are rovided with notches which form an ob ong opening 57, which registersor alines with a perforation 58 inthe bottom of .the carrier. The up er feed bar 30 is turned and bent forward y so that its lower end passes down through the holes or openings 57 and 58 and side walls59 of the carrier 56 vare provided with rectangular openings 60 and at .either side of these openings the side walls are alternately raised at 61 and depressed at 62' -to form circular bearings for short pivot pins 63. These pins serve as pivots for clutch members 64,. which are mounted thereon. The clutch members are substantially rightangled in shape, `the longer and horizontally disposed arms 65 entering the clutch'carrier The ' movement depresses the universal bar 17,

`the feed .bar 30.

through: the rectangular openings 60 and their inner ends abutting normally against opposite faces of .the lower lportion of the upper feed bar 30. The shorter arms 66 of the clutches are in normal position substantially vertical andare formed with rounded ends 67, the latter terminating about on a line with the bottom of the clutch carrier 56 and at-some distance from the sides of the same. 'y

'A short distance above the pivot 22, ythe lower feed bar 23 is oset'so as to come vertically beneath the clutchfearrier, as is best seen in Fig. '1. The upper end of the lower feed bar is bifurcated, the two arms 68 ofthe bifurcated portion being bent sidewise to loosely embrace the sides of the clutch carrier and the tops of the arms terminating somewhat below the top surface ofthe clutch carrier. The arms 68 are perforated at 69 to permit of the passage through them of the arms 65 of the clutches.' The size of the openings or erforations 69 is such as to permit of some ittle relative movement or vertical playvbetween the clutch members and in other words, the feed bar can move a short distance up or down before the tops or bottoms of the openings 69 contact with -the clutch arms 65. A sleeve`70 surrounds the standards 51 andthe arms The front and rear walls of the sleeve are formed with vertical slots 71 through which pass the stems of headed securing screws 72, which are screwed into tapped holes in the 'arms 52 of the standards. This construction permits the sleeve 'to be adjusted in various positions vertically of. the standard arms 52. The upper edge of the sleeve 70 is formed with a bevel 73.

The operation of the devices hereinbefore described is as follows:'-Considering first Figs. 1 to 5 inclusive, it will be noted that in these figures the sleeve 70 is adjusted in substantiallyits lowest position. Vv hen one of the Jringer or character keys 4 is adequately depressed, it lowers the key lever` 6, and through the link 8, draw-bar 9 and connecting rod 1st causes the typebar 15l to be swung about its pivot from normal position, bringing the type 15a to the printing point against the under side of the platen 45. it is deemed unnecessary to further describe the printing devices. r1`he draw bar 9 in its downward and the latter through the crank arms`18 vibrates the rock shaft 19, which in turn causes a downward movement of the forwardly eX- tending crank arm 21 which is fixe'dly vsecured onsaid rock shaft.` ,'lhe downward movement ofthe crank arm 21 causes the lower feed bar 23, which is pivoted to 'said crank arm at 22, to be depressed. ''he arms 68 of the lower feed bar acting, through the tops of the holesl 69, against the outer ends of the longer clutch larms 65, force theirends to g per feed bar 30, causing the latter to particiate in theldownward movement' ofthe 'ower feed bar 23. The downward movef ment of the upper feedbar 3() lowers the working face of the feed dog 32'out of contact with the working face of the' tooth .of the escapement wheel 34 with which -it is en# gaged, and permits it under the influence of its spring 33 to be lswung about its'pivot'l i in the direction of the arrow in Fig. 3`to1apo-` sition where it will contact with the next suc.` ceeding tooth of the escapement wheelfl' the same time the` holding dog 27 is swung into the 'path of the teeth of the escapement preventing the 'rotation of the, latterC `if now the finger key be released, theA universal bar starts on the return or latter half of its movement and the lower feed bar 23 will start to move upward under the influence of the restoring spring 20. The construction of the clutch carrier 56 is' such that the spring of its side walls4 5,9 develops sui'ii-d cient friction between the said. side walls and .the flangesl of the standard arms to hold the clutch carrier motionless betweenthe arms 52 of the standards at the beginning of. the return stroke. bottoms of the with the under side of the outer ends of the longer clutch arms 65, cause the arms 68 to actuate the clutch members, the inner endsv of the longer clutch arms will be swung downward about their pivots, releasing the end of the' upper feed bar 30 (as seen in Fig. 4). The release of the feed bar 30 permits the holding dog 27, under the iniiuence of the spring 35, to be swung out of the path of the teeth of the escapement wheel and back against a limiting stop 74 fixed to the bracketl mal position against its limiting stop `32h. The arrest of the feed dog brnigs the carriage to a stop after it has moved a single letter space, which movement it will beV notedv has taken place at the very beginning of the up.-

ward movementof the finger key.' After the disconnection of the' upper and lower-feed bars, the latter bar continues its upward "movement, swinging the inner endsof longer clutch arms Idownward until they contact with the bottom of the clutch carrier, after which .fthe latter participates in theupward ower limit of movement of the feed As soon, however, as the erforatlons 69, contacting movement until normal position is reached. Just before this'p'oi'nt is attained the to s of the outer ends of the longer arms 65 o the clutch members contact with the ends of the limiting screws 55 and the inner ends of the clutch members are swung upward about their pivots-until theyv again grip or clutch the lower portion of." the upper feed bar. The clutch members, their limiting stops and the feed bars will now be in the position shown in Fig. 6.

The mechanism as hitherto considered has been adjusted for feeding the carriage in the ordinary. manner, as it is commonly termed, that is for holding the carriage until the keystroke pleted and allowing the carriage to move in tter space direction some time during the' upward movement of the key. The play between'v the clutch members and the arms 68 is so limited that the upward movement of the various partsof the type action has hardly hmore than begun before the dog members of the escapement are released, .thus permitting the carriage -to feed. The.

feeding movement takes place' at the most advantageous instant in the'u -stroke of the key, no time being wasted an the parts being permitted' to return to normal position as` soon as possiblel before the beginning of the neXt key stroke and after the imprint of the type.

v Considering now more particularly Figs. 6 and 7, it will be noted that in these figures thefsleeve or collar 70 has been adjusted in working position, an operation which is accomplished by loosening the securing screws 72 raising the sleeve to the desired height and afterward tightening the screws to hold the sleeve in position. The mechanism is now adjusted for giving the reverse feed or "speed escapement, that is, for freeing the carriage from the control of the escapement members, 4so .that it may feed inv a letter space direction, during the downward strokelor depression of the finger key. The normal positions of the parts when thus set for the reverse feed is best shown in Fig. 6.y As the linger key is depressed the downward movement of the parts brings the rounded ends 67 of the shorter arms 66 into contact with the beveled edge 7 3 of the sleeve 70, Further depression of the finger key causes the beveled edge of the sleeve to cam the rounded-ends of the shorter clutch arms outwardly, the rounded ends as theyA m ve downwardly riding von the face of the sleeve. -As the" rounded ends are cammed outwardly, the inner ends of the 'longer arms 65 of the clutch members are swung downwardly about their pivots 63, freeing the lower end of the xupper feed bar (whichl has meanwhile pulled the dog members into substantially the position shown in Fig. 7) and thereby permitting the dog members to or depression has been comreturn to normal position and allowing the carriage to feed one tooth of the escapement wheel i letter space direction before the key has been fully depressed. After the upper and lower feed bars have been disconnected,- tlie latter, underthe influence of the finger key, continues its downward movement, carrying with itthe clutch carrier and the'clutch members to the bottom of the stroke and thereafter moving upwardly, earr ing with it the clutch carrier and the c utch members, the ro'unded ends 67 riding art of the time on the 'face of the sleeve 70.

ust before normal position is reached in the course of the upward movement of the parts, the tops of the outer portions ofthe longer arms of the clutch members-contact with -the ends of the limiting screws 55. Further upward movement swings the inner ends of the longer arms or grippers into gripping position against the feed bar 30, so that when the parts reach the limit of their upward movement they are again in the position shown in Fig. 6.

It will be noted that the sleeve 70 may be adjusted to cause the feed bar 30 to be freed and the carriage to be fed a single. letter space at any point of the downward movenient of the finger key, it being only necessary that this release of the feed bar 30 shall take place after the latter has moved downward far enough to free the tip,I of the feed l dog 32 from contact with the working face of the tooth of the escapement wheel. It is possible,l therefore, to adjust the parts so that any desired speed of escapement within practical limits may be attained.

The clutch mechanism hitherto described comprises two clutching o rgripping members. In Figs. 11 to 16 inclusive, l have illustrated another construction of clutch embodying a single gri ping member. This modified form of clutc may be employed instead of the form h ereinbefore described where the upper feed rod, asindicated by the numeral 75, is cylindrical in form instead of being rectangular in cross section as is the upper feed bar 30 illustrated in Figs. 1 to 10. When this style 'of clutch is used a cu shaped base-piece 76 is secured in a suitab e manner, as by headed screws.7 7 to the to of the rear ortion of the base 1 of the machine. Closely itt-ing over the cup-like base 76 so as to be held in position by the friction between the outer surface of the said base and its own inner surface, is a hollow cylindrical casing 7 8 the top whereof is covered by a cap or cover 79. The latter is perforated to permit of the passage of the up er feed rod 75, which is guided by the sides of the'said perforation. The base 76 has its bottom perforated to permit of the passage therethrough of the lower feed bar 8() which is bifurcated at its upper end, the arms 81 of the bifurcation embracing and guiding the lower end of the feedrod 75.

ceases Suitably secured, as by rivets 82, to tbe upper portions of the arms 8.1, is a clutch holder 83 which 1s formed at one side with two up-k right earsSui, the latterbeing perforated to receive the short pivot rod 85.- Pivoted on the rod 85 is the. clutchmember S6 which casing 78 is formed with two vertical slots 90 and 91 .which are connected by a horizontal l ln assembling the parts, the tail end 8S of the clutch member is introduced-into slot 92.

the upper slot and then by turning the casing in the .direction of the arrow in said Fig. 16, the tailend, passing through the horizontal slot 92, is introduced into the lower vertical slot 91 after which the-pivot rod 85 is shoved Vinto place. The gripping arm 87, as best appears in Fig. 14, has a central disk portion 93 .which is perforated at 94 topermit the rod 7 5 to pass therethrough. As seen most clearly in Fig.- 11, the upper edge ofthe right-hand sidel of the perforation 84 is rounded off, as is the lower edge of the lefthand side of said perforation. Suit-ablyatitached to the upper portion of the inner wall ofthe casing 7 8 at the left hand side is a friction spring 96 Whichis adjustable by means 4of a headed screw. 9.7 which is screwed through the wall of the casing. A cylindrical cam sleeve 98 having its upperedge beveled at 99 surrounds the easing 7 3 and `is vertically adjustable thereon by 'means of the slot 100 and screw 101.

In Fig. v13 the cam sleeve 98 is shown in lowered position where it will nota'ffeet the clutching or gripping member 85, the mechanism beingr set for ordinary spacing.

Upon the depression of the finger key vor of the spacingbar, the lower feed bar SO is dey pressed in thesame manner as has been .hitherto described in connection with the lower feedbar 23. T he sides ofthe perforation 94 gripping the upper feed rod cause the latter tobe lowered in 'unison with the feed bar 80. lt is to be understood that the upper end of the feed rod 75 is connected with the dog members 27 .and 32 in a manner similar to that hitherto described as applied tothe upper .feed bar 30, so that the loose dog 32 is .disengaged from the escapement wheel 34 Tand the rigid dog is brought into the path of the same by the downward movement of the said feed rod 75. As soon as the upward movement of the finger key begins, the feed bar begins to move upward and the end lof the gripping arm 87 of the clutch member,

which end is in contact with the friction' spring 96, is so retarded by the said spring as to cause the gripping arm to .be swung downwardly about its pivot untll tue gripping arm is substantially horizontal y(as shown by the A .ping arm 104 of theclutch member.

dotted lines in Fig. 13), whereupon the edges of the perforation 94 cease to clutch or grip the feed rod 75. Thusjfreed fromthejclutching member, the feed rod `75 is simultaneously diseonnectedfrom' the'feed bar 8Ol and is permitted to move"upwardr and cause a letter space feed of thelcarriage in advance of the further upward movement of the finger key and the feed bar 30E During the upward movement of the feedl bar 80 after 'the feed rod 75 has been'disconneetedfrom it, the end of the gripping arm 87 is swung about its pivot downward below" the horizontalby the action of the spring 96, but the gripping arm in this p osition is preventedfrom gripping or clutching the feed rod 75 by reason of the fact that the contacting edges ofthe perfo#- ration 94 are rounded or cutaway as seen in Fig. '11, and as has beenhitherto described. As the feed bar 80 nears the limit of 'upward movement, the top of'y the outer portion of the gripping bar 87 contacts with the top cf v and l2, it will be notedj` that the cam sleeve 98 has been adjusted to effect `the reverse feed The moving parts inthis ease move downward from the normal position. shown in 11 until the rounded yportion 89 of the tail of the clutch member contacts with the beveled edge 99 of the camsleeve. Uponl further downward movement `the tail of the clutch member is cammedoutwardly by the beveled edge 99 and rides down over the outside surface of the sleeve 98, bringing the arm 87 to a horizontal position and causing the feed rod 75 to be released before the completion of the lrey depression.

. In Fig. 17 is illustrated a single clutch member similarto that shown in 11 eX- cept that removable gripping shoes 102 are mounted on tongues 103 Jformed on the grlirlp- T is construction increases the areav of contacting surface and reduces thewear vof the'parts to a minimum. L;

In Fig. 18 is shown afs'ingle clutch member having a cam faced gripping arm 105 pivoted in the side of a carrier '106 which is operated in a manner similar toth'at of ldigs.y 1 `to 10. The. 'carriage in this instance, however, .1s formed, on the side opposite the cam, with projections '107 Whichabut against theside of the upper feed bar 30 so thaty when the arm 105 lis in operative position the feed bar is gripped between thecam `105 andthe pro- 1'25.

l am aware that it isnQtjbrQadly new'to change an escapement mechanism which normally feeds the carriage during the return movement of the'dinger keyfso as to cause the 'mechanisnr toy feed the'carriage feed to the ordinary form.

while the finger key is being depressed; :or is it'new to reverse the operation and cham-e the escapement so as to cause the carriage to be fed a letter space during the return movement of the finger key instead of during the depression of the same. So far as I am aware, however, the contrivances hitherto devised for this purpose have all made use of the general principle of altering .the character of the escapement mechanism either by modifying the characteristics of the escapeme'nt members, or else by employingl an ad: ditional member, so as to change the relative positions of members performing particular functions. One type of escapement mechanism comprises essentially a feed dog, a holding,T dog and a rack, straight, segmental or circular, One form ofthis type or style of escapement is embodied in the machine illustrated in the drawings forming partof the specification. The method employed to change the feed with this form may,` in general terms, be described as follows: The loose or feed member or dog is, when the escapement is adjusted for the ordinary feed, normally in engagement with the, escapement wheel or circular feed rack, which latter is continuously connected with the carriage during` the letter spacing operation. When 'a key is depressed the-feed dog is moved forward out of engagement with the rack and vibrated in feeding direction by its spring. At the same time the rear or holding` member or dog` is moved forward into engagement with the third member or rack. In this case the feeding movement of the carriage does not occur until, on the return movement of the dogs, the rear or 'holding dog disengages and the forward or feed dog reneiages with the third member or rack. To reverse the feed, various devices are employed to change the feed or loose dog into a holding or rigid dog, and to change the holding dog into afeed dog. This accomplished, the feed of the carriage takes place as. soon as the forward dog, which is now the holding; member, is drawn out of engagement with the third member or rack and the rear or, in this case, feci dog' is drawn into en sagement .with the third member or rack.

There the escapement members comprise two segmental, circular or straight racks and a single dog, devices of similar function are made use of to change the feed from ordinary to reverse, and vice versa. In other words, the feed rack is fixed and theixed rack is loosened to reverse the feed,'. and the operation is reversed to restore4 the In my in vention, however, it will be noted that the relations of the escapement members or devices are not altered in changing from the ordinary feed to the reverse feed, or vice versa. The feed member or dos' or the ordinary feed is likewise the feed dog em- -points in their paths of travel.

loyed with the reverse feed, and the holding member or dog employed with the ordinary feed is likewise the same holding' dog that is employed witlrthe reverse feedH the relation between the two dogs being the Same in both cases, and their relation with the third escapement member or rack remaining unaltered.

It is by providing means to automatically disconnect certain parts of the carriage feeding mechanism during the finger key movement, and by altering, relatively, the time at which this disconnection takes place that I effect the change of feed. The disconnection or separation of the parts is complete and as soon as it .occurs the separated parts are free to move independently.

When an escapement mechanism of the ordinary style is employed, various devices have been resorted to in order to secure a quick release of the carriage from the escapement members after the impact of the type against the platen and immediately after the return movement of the key is begun. Some of these devices 4have made use of dog members which are frictionally connected with the dog rocker and are limited by stops so as to move with the dog rocker during only a part of its 'movement -Another methodmade use of to effect the same result is to frictionally mount upon the dogg,` rocker a member which serves as a stop for one of the dogs, and this stop member is so limited as to participate only in part in the movement of the dog rocker.

By providing means to completely separate or disconnect certain of the escapement members from the universal bar, I secure a quick release without employing limiting means or stopspvhich latter are, so far as I am aware, essential tothe devices hitherto employed to effect such release. This construction has an additional advantage :where it is employed, with type bar machines in' which theuniversal bar contacts directly with key levers to which connecting wires are attached at varying distances from the 'center of motion of said key levers, as in the In machines oi' this class 1t is necessary to adjust separately each Remington typewriter.

key'lever in relation to the universal bar, in order that the escapement may take-place when the type bars are at corresponding By my construction such adjustment is` unnecessary. Furthermore, it is )os-sible to move the universal bar nearer the fulcrum of the key levers, as'only motion sufficient to effect the release of the stepping dog is required. This would make the key action'much easier.

As the-mechanism herein set forth includes many features which are broadly new, I do not wish it to be considered that theinven'- 'tion is limited to the precise details of construction and arrangement described and said automatic disconnecting. means being shown, since many changes may be made without departing from the spirit of the invention. Some parts of the invention may be used Without others. lVhile l have shown the same as applied to a New Century Caligraph typewriting` machine, it Will, of course, be understood that it is applicable to other forms of Writing machines.

What I claim as new and desire to secure by Letters Patent, is
